Helsinki studies nuclear district heating option
Nuclear district heating is the most cost-efficient way to reduce the Helsinki metropolitan area’s carbon dioxide emissions from heat and power production after 2020. So concludes a study of the environmental impacts, technical feasibility and profitability of nuclear district heat in the Helsinki metropolitan area carried out by Pöyry at Finnish energy company Fortum’s request.
The district heat would be produced at the proposed Loviisa 3 nuclear power plant unit and transferred to the Helsinki metropolitan area. The Finnish Government is expected to decide this year whether Loviisa 3 can be built.
The Pöyry study compared three alternative scenarios for producing district heat for the Helsinki metropolitan area: a carbon scenario based on the current production structure, a biomass-based bio-scenario and a nuclear district heat scenario. In the nuclear district heat scenario, district heat is transferred to the Helsinki metropolitan area via a 100 km transfer pipeline, and the heat is distributed to Helsinki’s network at several different connection points.
The Pöyry study indicates that the nuclear district heat option would provide the biggest decrease in carbon dioxide emissions. In the nuclear district heat scenario, the Helsinki metropolitan area’s post-2020 carbon dioxide emissions from energy production would be about 60%—75% less than in 1990, and other emissions in the Helsinki area would also decrease significantly.
The study found the nuclear district heat scenario to be the most lucrative option. In the bio-scenario, heat production costs, including the needed infrastructure investments, decrease by €7/MWh and in the nuclear district heat scenario by €18—26/MWh, compared to the coal scenario.
‘By utilising the district heat produced by Loviisa 3, Finland could reduce 4 million tonnes of carbon dioxide emissions per year and cover a large part of its emissions reduction obligations without public financing. This is an unprecedented opportunity for the players in the Helsinki metropolitan area to resolve their energy and climate challenges in a profitable manner’, says Tapio Kuula, President and CEO, Fortum Corporation.
Wärtsilä wins on-site plant orders from Turkey
Decentralized power generation solutions provider Wärtsilä has signed agreements to supply the equipment for three gas-fuelled cogeneration plants under construction in Turkey. The new plants are scheduled to be operational in the spring and summer of 2010.
Wärtsilä is to supply the equipment for the Naksan power plant project in Gaziantep, located close to the Syrian border in the southeast of Turkey. A second installation is for the Marmara Pamuklu power station in Corlu, close to Tekirdag, located in the northwest of Turkey. Most recently, the company has been contracted to supply equipment for the H.G. Enerji power plant project in Gediz, in the province of Kütahya in the Aegean region of the country.
The Naksan power plant project is being developed by Naksan Plastik San Ve Tic A/S, which will use the electricity and heat generated by the plant for its own packaging manufacturing processes. Wärtsilä will supply the engineering and equipment, consisting of two Wärtsilä 20V34SG engines running on gas, as well as the compressed air system, radiators and charge air filters. The combined output will be approximately 18 MW.
The second contract is for three Wärtsilä 20V34SG engines to be installed in an
extension to the Marmara Pamuklu power station in Corlu, Turkey. The engines will be run on natural gas and will have a combined output of 25 MW. The contract has been awarded by Marmara Pamuklu Mensucat San ve Tic A/S, a textile and paper producer which will use heat from the power plant for its paper and combined cycle processing.

Hydro-Quebec accepts biomass bids
Canada’s Hydro-Quebec has accepted eight bids for a total of 61 MW of generating capacity in response to its April call to purchase power generated by biomass cogeneration plants in Quebec.
Over the coming months, Hydro-Quebec Distribution will work with the project proponents to finalize the contracts.
The average price of the winning bids is 11.2 cents/kWh, including 0.4 cents/kWh for transmission costs. The projects call for capital expenditure of about $180 million, plus another $39 million for transmission infrastructure.
Rooftop cogen system for Deutsche Börse
Jenbacher cogeneration technology has been installed on the rooftop of the new office tower for Deutsche Börse Group in Eschborn, near Frankfurt, Germany, providing one of the world’s leading exchange organizations with a secure and efficient supply of energy.
For the new rooftop CHP project, GE supplied project developer Wilhelm Theis with two JMS 412 Jenbacher cogeneration modules. In warmer months, hot water from the cooling circuit of the two cogeneration plants will serve as drive energy for two absorption chiller devices. During cold seasons, this thermal power will be utilized to meet the building’s heating requirements.
The 1.6 MWe plant will be fuelled by natural gas and surplus electricity will be sent to the regional grid to increase energy reliability for the Frankfurt area.
The cogeneration plant is scheduled to begin commercial operation in the summer.
Paris to upgrade Ivry waste-to-energy plant
Inova France, the French subsidiary of the Swiss specialist for energy-from-waste technology Von Roll Inova, has been awarded a second major contract by SYCTOM, the waste management syndicate for Paris and operator of the Issy-les-Moulinaux incinerator recently fitted with Inova equipment.
With an annual capacity of 730,000 tonnes of household waste, the existing Ivry-sur-Seine plant is France’s largest facility of this kind. Its two trains each produce 100 tonnes of steam per hour, used for district heating and for generating electricity. The thermal and electric energy is distributed to some 100,000 homes. The purpose of the renovation project is to safeguard the plant’s functional integrity for the next ten years.
Von Roll Inova will upgrade the two trains of the existing Ivry plant with state-of-the-art technology. The contract involves the renovation of the combustion and steam generation systems.
The modernization contract is part of an ambitious plan developed by SYCTOM to establish a new ecological and technological platform for its long-term operations in Greater Paris.
On-site wind installation for US Abbey
US-based Sustainable Energy Developments (SED) has completed the installation of a 100 kW on-site wind turbine at Mount Saint Mary’s Abbey in Wrentham, Massachusetts, US.
Sister Mariann Garrity of the Abbey approached SED in 2007 about the possibility of a wind project at the Monastery where she and nearly 50 other Cistercian Nuns live and work. The Sisters at Mount Saint Mary’s Abbey are aware of rising electricity costs and of their own carbon footprint. The new wind turbine will offset more than 50% of their energy needs with wind-generated electricity.
A feasibility study completed by SED in determined that a 100 kW wind turbine would be the most cost effective fit for the Abbey. The Massachusetts Renewable Energy Trust awarded the Abbey grants to help fund the feasibility study, design activities and the recently completed construction of the wind turbine. The Abbey received donations from local foundations and even sold some of its land in order to help fund the costs of the project. The Sisters will continue to hold fundraisers in an effort to pay off their remaining project obligations.
The wind turbine, a Northwind 100, is manufactured in Barre, Vermont by Northern Power Systems. Founded in 2002, SED is an Ontario, New York-based decentralized wind power company and has installed more than 3 MW of wind projects throughout the Northeastern US.
Cogeneration in Spain
A subsidiary of Foster Wheeler’s Global Power Group has been awarded a contract to design, supply and erect a heat recovery steam generator (HRSG) by the Spanish company, REPSOL PETROLEO, for integration into a cogeneration plant being built at the REPSOL Cartagena Refinery in Murcia, Spain.
The HRSG will be coupled with a GE PG-6581 gas turbine and recover heat from the gas discharge stream, producing high-pressure and medium-pressure steam for use in refinery processes, and electricity generation at the Cartagena facility.
US Landfill gas system earns EPA award
The US Environmental Protection Agency (EPA) has honoured the city of Sioux Falls and ethanol producer POET for a landfill gas project that provides significant amounts of energy for process steam at POET Biorefining’ site at Chancellor, South Dakota, US.
The city’s 11 mile pipeline, transports methane from waste at the Sioux Falls Regional Sanitary Landfill to the Chancellor plant. The methane in conjunction with a waste wood boiler, produces process steam for ethanol production. The methane currently offsets 15% of the plant’s energy needs and, as the supply of landfill gas increases, that is expected to double by 2025.
POET pays the city for the methane, providing a revenue from gas that had previously been flared at the landfill.
Methane has more than 20 times the global warming potential of carbon dioxide. Instead of allowing the gas to escape into the air, it can be captured, converted, and used as an energy source through projects such as this. Using landfill gas also reduces odours and other hazards associated with emissions, while preventing methane from migrating into the atmosphere.
CHP for wastewater treatment project in Mexico
The Netherlands-based Green Gas International has joined a consortium with IDEAL, ACCIONA, Atlatec, ICA and DYCUS which has concluded a 25 year agreement for the construction and operation of one of the world’s largest wastewater treatment plants with National Water Commission of Mexico. As part of the consortium, Green Gas will provide their technical expertise for the construction and operation of the planned CHP plants.
The project will be located in the town of Atotonilco in Hidalgo State, 60 km north of Mexico City. Currently in this area only 12% of waste water is treated per day. The new plant will have the capacity to treat 3.6 million tonnes of water per day which will equate to around 60% of the area’s wastewater resource.
Green Gas will provide engineering services and operation and maintenance supervision in relation to the CHP component of the project. The CHP plants will convert methane that is produced from the waste water treatment utilization process into electricity and heat. The CHP plants will potentially have 33 MW of capacity and the capability to reduce emissions in excess of 1 million tonnes of carbon dioxide equivalent per year, says the company.
Construction of the $710 million wastewater plant is scheduled by the company to start by the end of the first quarter of this year.
Energizing Asia Pacific fuel cells markets — F&S
Many countries in the Asia Pacific region aim to have 8%—20% of renewable energy in their energy mix by 2020 to 2025, making the region an option for the implementation of renewable power generation and, thereby, the development of stationary fuel cells.
So run the conclusions of a report from Frost & Sullivan: Asia Pacific Fuel Cells Markets, which finds that the stationary fuel cells segment earned revenues of $142 million in 2008 and estimates this to reach $1.9 billion in 2015.
The fuel cells market is currently holding on to its market position mainly on the strength of government subsides, incentives, and favourable policies. The eventual adoption of the fuel cell as the power source of choice will depend on how aggressively and effectively local governments market it, says F&S. ‘As with any other new product, the initial costs of technology, low end-user awareness, and the lack of a proven track record of continuous and reliable operations restrict the degree of adoption of fuel cells,’ says Frost & Sullivan Program Manager Irina Sidneva.
In Japan, the Ministry of Economy, Trade and Industry is running a millennium project on automotive and residential fuel cell markets. In 2009, the emphasis of the third phase of the project is on the commercialization of fuel cells — on creating positive market conditions to motivate mass adoption. Meanwhile, the Ministry of Knowledge Economy (MKE) in South Korea is supporting extended trials and diffusion of the product to stimulate wider uptake. While ANZ and several SEA countries are still in the planning phase of fuel cell technology rollouts, Singapore, Malaysia and Thailand are actively developing fuel cells R&D capabilities. In SEA, the pride of place goes to Singapore, with its government striving to position the country as a regional hub for fuel cell technology R&D and application.
However, reports F&S, the demand is still limited from most other countries due to inadequate assistance from the regional governments and the high initial costs of the technology. Moreover, fuel cells have an added disadvantage of competing with mature products such as diesel and gas engines, generator sets, and batteries.
Four Italian hospitals turn to cogen units from GE
Hospitals in four Italian cities have signed contracts to install GE’s Jenbacher cogeneration systems to improve their energy efficiency and reduce their operational costs. The four hospitals planning to install new CHP systems are located in Alessandria, Milan, Cuneo and Conegliano (Treviso).
As a result of the hospital district heating projects, these cities will benefit from a total displacement of the equivalent of 20,000 tonnes of carbon dioxide every year, says GE. The systems will also enhance local energy security.
The new hospital CHP contracts call for GE to supply:
- Two 1.1 MW, J416 gas engines for the Hospital of Alessandria — the engines will power a system able to supply energy and heat for the 650 bed facility. The system started working at the end of October last year.
- One 600 kW, J312 Jenbacher engine for the Hospital of Conegliano (Treviso), which holds approximately 400 beds. The system will begin operating early this year.
- Two 1.4 MW, J420 units will be installed at the Fondazione Ospedale Maggiore Policlinico, Mangiagalli e Regina Elena in Milan. The system will begin operating by the end of the year.
- One 1 MW, J320 Jenbacher engine for the Azienda Ospedaliera S. Croce e Carle of Cuneo.
In total, and recognizing the advantages of CHP, 34 hospitals in Padova, Varese and Brindisi and other cities in Italy have installed Jenbacher cogeneration gas engines, adds the company.
‘District heating technology is widely used in Northern Europe and has spread throughout Italy in the last few years,’ said Mario Artoni, general manager — Italy for GE Power & Water’s Jenbacher gas engines. ‘Because the costs and reliability of energy are major concerns for hospitals, on-site CHP systems play a fundamental role by increasing energy efficiency and security while reducing the release of environmentally damaging exhaust gases.’
O&M contract for wÄrtsilÄ
Finland’s Wärtsilä has been awarded an operations and maintenance (O&M) contract for a coal-fired on-site power plant in India, at global producer of zinc and lead, Hindustan Zinc.
The contract covers the complete O&M of the 160 MW coal-fired power plant, including the coal and ash handling facilities and the on-site demineralised water plant.
Nuon takes over Dutch CHP plant from Electrabel
Nuon, the Business group Benelux of the Vattenfall Group, has signed an agreement with Electrabel, which is a subsidiary of the GDF SUEZ group, to take over its natural gas-fired CHP plant in Almere, the Netherlands. The CHP plant comprises two units of 60 MW each and supplies heat to Nuon for district heating for 43,000 homes in Almere.
‘District heating is an environmentally-friendly method of heating without a central heating boiler and saves the company a significant amount of carbon dioxide emissions,’ says Øystein Løseth, CEO of Nuon. ‘By purchasing this CHP plant, Nuon aims to guarantee the security of supply of heat to the residents.’
The transaction still needs to be approved by the Nma.
300 MW cogen project for Mexican gas plant
Gas turbine technology from GE is to be used to convert a conventional power plant into the first large-scale cogeneration plant in Mexico, in support of the Mexican government’s initiative to promote cogeneration as a key step in improving the efficiency of the country’s energy infrastructure. The new plant will offer increased efficiency and will supply process steam to one of the country’s most important natural gas complexes.
The new 300 MW cogeneration plant will be owned by a consortium made up of Abener and Abengoa Mexico and will supply steam and power to PEMEX, Mexico’s state-owned oil and gas company, for use at PEMEX’s existing natural gas processing facility in Tabasco.
GE will supply two Frame 7FA gas turbines, which have the capability to burn natural gas with high nitrogen content, which fits the profile of the fuel available at the Nuevo PEMEX site. In addition, GE has signed a 20-year contractual service agreement to provide a full range of plant services, including planned and unplanned maintenance..

The two companies have agreed to buy MATEP for approximately $320 million in cash, pending necessary regulatory approvals.
Once the acquisition has been approved, Veolia Energy, which has a minority ownership interest in the joint venture, will assume responsibility for MATEP operations. The company operates the largest portfolio of district energy (heating, cooling and cogeneration) networks in the US, with systems in the central business districts of 14 cities across the country.
Finnish companies supply biomass CHP to Belgium
Finland’s Metso Corporation is to supply a biomass power plant for a CHP facility being built in the municipality of Ham in the Belgian province of Limburg by 4HamCogen, a subsidiary of Belgian biomass-to-energy project developer 4Energy Invest.
The modular biomass power plant will utilize bubbling fluidized bed (BFB) technology and will use non-contaminated biomass as the main fuel. With the new cogeneration plant, 4HamCogen will feed 8.4 MW of electricity into the distribution grid and will be able to deliver up to 14 MW of heat.
The power plant will be delivered by the Metso-Wärtsilä joint venture MW Power, and the plant automation system by Metso’s Automation business line. Start-up of the plant is scheduled for Q2 in 2011.
Biofuel CHP scheme for UK Industry estate
Plans for a new CHP scheme to serve an industrial estate on Teesside, north-eastern England, have been revealed by a local developer. County Durham company Banks Developments is proposing a development to be located around the village of Stillington, to the north west of Stockton.
The CHP scheme, capable of producing up to 4 MW of power, would be located next to existing businesses on the Stillington Industrial Estate, in order to provide them with both heat and electricity generated from renewable fuels such as biodiesel.
If plans are approved this may enable community groups to install other forms of renewable energy and other community projects, according to the developer.
Biofuelled CHP plant for UK Port of Dover
REG Bio-Power, a subsidiary of the UK’s Renewable Energy Generation, has signed a five year contract with the Port of Dover to supply electricity and heat from its biofuel CHP system.
Under the terms of the agreement, REG Bio-Power will install a 150 kW Volvo Genset to supply a proportion of the Port’s annual heat and electrical demand, which totals around 6-8 MW. Upon successful implementation of this project, both parties have agreed to discuss a further roll out of similar operations across the Port. Construction of the first plant is underway.
Bio-Power says it is meeting a growing demand for decentralized electricity on industrial and commercial sites, using its proprietary fuel, known as LF100, which is refined from used vegetable cooking oil to produce renewable electricity.
The agreement with the Port of Dover, REG Bio-Power’s first independent commercial CHP contract, has fixed electricity prices for the first three years. The heat and electricity produced makes the scheme eligible for government-backed financial support, in the form of two Renewable Obligation Certificates per MWh generated.
Belgian metals company looks to on-site wind
Electrabel and metal transformation and coatings company NV Bekaert are establishing a partnership for the construction of an on-site wind farm on the Bekaert site in Zwevegem, Belgium. The two companies are to study the possibilities of on-site power generation, both in Belgium and abroad, as well as to ascertain the best energy conservation solutions for Bekaert’s activities.
The first phase of the partnership will, after obtaining the necessary permits, be a wind turbine project on the Bekaert site at Zwevegem, whose power generation will be fully consumed by Bekaert. The construction is scheduled to begin at the end of 2011. The same plan is being examined for the Bekaert sites abroad.
Thanks to this cooperation, Electrabel will further its desire to be more than a supplier to its customers. By providing Bekaert with solutions tailored to achieve energy efficiency, the rational use of energy, audits and energy production from renewable sources, the company will enable its customers to have better control over their energy costs.
On-site wind turbine for UK retailer?
UK supermarket retailer ASDA is submitting plans to Redcar and Cleveland Borough Council in north-eastern England to erect a single on-site wind turbine at one of its distribution centre in Teesport.
The proposed turbine would produce up to 150% of the centre’s energy needs, with surplus electricity will be sold back to the electricity grid, thus delivering ASDA’s commitment to the environment and securing energy from green sources.
The proposal would see the erection of a single wind turbine, with a maximum height to the blade tip of 100 m (74 m high tower). The plans also include the creation of a temporary construction area and underground cables to link up with the distribution centre to provide it with renewable electricity.
Biofuelled cogeneration at UK gas distribution point
UK-based renewable power company Blue-NG has ordered two MAN engines to power two highly efficient and innovative power plants in London, UK, where heat from the bio-fuelled engines is used in the process of natural gas pressure reduction. Each plant, located in the Southall and Beckton districts, will have one MAN B&W 7K60MC-S engine at its heart, manufactured by MAN Diesel’s Polish licensee H Cegielski — Poznan.
The heat from the two plants will be used in the gas pre-heating process, a necessary part of the pressure reduction process for liquid natural gas, and will supply renewable electricity. Blue-NG signed a turnkey construction contract with Land & Marine Project Engineering for the design and construction of the power plants last year.
The engines represent the latest generation of the popular, two-stroke, low-speed MAN B&W K60MC-S engine and will run on crude rapeseed oil. Each engine develops 13.9 MW at 150 rpm and is installed with an Organic Rankine Cycle (ORC) turbine and ‘turbo compound system’ for increased efficiency.
Blue-NG is builds and operates generating plants that produce electricity and heat locally. The company is a joint venture between the National Grid, the UK’s gas and power distribution company, and 2OC, a company well known in geothermal energy and natural gas pressure reduction station projects.
Funding for microturbine projects in Pennsylvania
Two of the nine projects in Pennsylvania, US, selected for $12 million in American Recovery and Reinvestment Act Funding were submitted using technology from Capstone Turbine Corporation, says the company. The projects, which will receive $1.6 million of the total $12 million awarded, will see microturbine-based CHP systems installed at two industrial sites.
The projects were developed by E-Finity Distributed Generation, Capstone’s distributor for the Mid-Atlantic region.
E-Finity will supply, integrate and maintain the Capstone C1000 to be located at Mount Joy Wire Corp. in Mount Joy, Pennsylvania. The wire manufacturer will use the natural gas-fuelled C1000 in a CHP application that will provide 1 MW of electricity to the facility. Heat produced by the turbine will be used to heat water on-site.
E-Finity also will supply, integrate and maintain the second CHP project at Philadelphia Gas Works headquarters in downtown Philadelphia. Philadelphia Gas has had a Capstone C200 natural gas turbine installed and will use the device to educate its customers about the benefits of CHP. Waste heat energy from the turbine will heat water that is then run through an absorption chiller to create air conditioning for the facility.
E-Finity has recently commissioned the first Capstone microturbines in Philadelphia at the Four Seasons Hotel and recently completed projects at The Bridge Business Center, Salem College and a compressor station for Dominion Transmission.
Biogas plant supplies L’Oreal in Belgium
A unique industrial biogas-to-energy cogeneration plant has been unveiled at a manufacturing facility owned by L’Oreal in Libramont, Belgium. The on-site technology means that the production site is independent of the public electricity and natural gas grid.
The project is the result of cooperation between the Belgian developer of sustainable energy, Bio Energie Europa, energy company Eneco and L’Oreal.
An industrial biogas plant was built close to the L’Oreal plant in Libramont. Biomass, from local farmers and the agro alimentary industry, is collected in a sealed tank, in which bacteria convert the biomass into methane through fermentation. This biogas is then transported through a 600 metre subterranean pipeline.
The biogas bought by L’Oreal is used in three cogeneration engines which produce both steam and power, all of which is used by the factory, with any excess power exported to the public grid.
For L’Oreal, completion of the project marks an important step towards achieving its goal of reducing its worldwide emissions of carbon dioxide by over 50% by 2015.
New York co-op selects CHP system
Clean on-site energy supply company American DG Energy Inc has signed agreements to provide green energy solutions to The Forest Hills, a 120 unit housing co-operative, located in Queens, New York, US. American DG is to install a 100 kW CHP energy system and a 200 tonne natural gas engine driven chiller at the property. The value of the deals to American DG Energy is $2.81 million.
The company is installing a new chiller to replace a 45 year old steam chiller, which was both costly to run and an inefficient provider of chilled water and space cooling for the property. The new gas engine driven chiller will generate more chilled water, allowing The Forest Hills also to decommission two old steam boilers, which were already at the end of their useful life and could not be used any longer.
Instead of purchasing the new chiller, The Forest Hills opted for an ‘on-site utility’ arrangement by American DG, under which The Forest Hills will pay only for the energy it uses and will avoid additional operating costs. American DG Energy will handle all service, maintenance and repair for the project.
In addition to installing the chiller, American DG Energy is installing a 100 kW CHP system to provide electricity and hot water for space heating and domestic hot water use at the housing co-operative. The Forest Hills opted to purchase the CHP system, but has selected American DG Energy to operate and maintain the system.
Biomass and micro-CHP to help ‘decarbonize’ the UK
In a world where we have become focused on a target to achieve 15% of our energy from renewable sources by 2020, CHP delivers a credible route to start decarbonizing the remaining 85% of our economy which will still be dependent upon fossil fuels. Graham Meeks, director of the UK CHP Association, summed up the case for CHP thus at their annual conference in London, November 2009.
Earlier in the day, RWE npower Cogen’s Phil Piddington spoke of the effects of the recession on the CHP industry — and the wider industrial base — in both Britain and Europe. While a couple of his customers had suffered in the worst possible way by actually closing down sites that incorporate major CHP plants, other companies used the recession to take a hard strategic look at their businesses and how to ensure their survival. Perhaps counter-intuitively, this may involve increased investment in cost-cutting on-site power plants.
Piddington described how npower has recently started site clearance work in Markinch, Fife, Scotland for a new, biomass-fuelled CHP to serve the Tullis Russell paper mill there. The proposed, 45 MWe plant, which will replace a 60-year old coal-fired CHP plant at the site, will burn around 400,000 tonnes per year of biomass, comprising both forestry waste products and waste wood recovered from city waste streams, largely from the cities of Glasgow and Edinburgh. Wood from both sources will be made into wood chips and pumped into storage silos before being burned in circulating fluidized bed boilers to deliver both power and steam.
Development has been helped by a substantial grant from the Scottish Government’s Regional Assistance Fund, and the project will attract ‘double ROCs’ — twice the renewable incentive available to some other technologies. The plant would not be going ahead without this help, said Piddington, but Britain may lose out to other countries in Europe with stronger support mechanisms for CHP.
Piddington concluded now is still a good time to plan biomass-to-CHP plants — and to end the practice of sending wood to landfill. Despite its difficulties, there is scope in the UK for perhaps 10-12 plants.
Switching scale to micro-CHP units with an electrical output of around 1 kW which are being developed to serve individual homes, Yan Evans of Baxi spoke confidently of his company’s product being commercially available in the UK ‘by the end of the second quarter of 2010.’ Given that domestic-scale micro-CHP has been promised for ‘next year’ by a number of developers over a number of years, Evans’ claim was bold indeed.
‘Bluegen’ CHP unit for Japan
Developer of fuel cell-based power generation systems, Ceramic Fuel Cells Limited has announced that home heating manufacturer Paloma will install one of its ‘BlueGen’ power and heating units in its warehouse and sales office in Sapporo, Japan.
Under the agreement with Paloma, Ceramic Fuel Cells will supply a BlueGen unit for a 12 month demonstration, beginning in the first quarter of 2010. BlueGen will be connected to the existing Japanese natural gas pipeline and the power grid.
In September 2008 Ceramic Fuel Cells installed a demonstration system at Paloma’s facilities in Nagoya. The unit was successfully operated on one fuel cell stack for the agreed six month trial, until the end of March 2009. Ceramic is also deploying fuel cell products with utility customers and appliance companies in Germany, France and the UK, says the company.
Engine CHP replaces turbine at UK hospital
City Hospitals in Sunderland, north-eastern UK is to cut carbon emissions and energy costs with a new 1.55 MW CHP system from UK cogeneration specialist ENER-G.
The hospital is targeted to recover the £600,000 capital cost of its new CHP system in less than three years. The Trust has also installed three high efficiency water boilers, replacing old steam boilers. The entire installation will make carbon savings of around 3400 tonnes per year.
The new system, which replaces a gas turbine powered CHP unit also supplied by ENER-G 16 years ago, is among the first installations in Europe by ENER-G of its new 1.55 MW MTU unit powered by a natural gas engine. The MTU reciprocating unit develops 1550 kWe, compared to the 1050 kWe output of the hospital’s previous gas turbine engine. The outgoing gas turbine power unit has enabled carbon savings of around 30,000 tonnes over 16 years.
This latest project follows the installation by ENER-G of CHP systems at major hospitals including Birmingham Heartlands, Solihull Hospital and the Royal Shrewsbury.
As Europe’s biggest employer, the NHS contributes approximately 3% of England’s total carbon dioxide emissions, so there is a powerful need to implement effective carbon abatement strategies like CHP. A political mandate has now been set through proposals for a new Carbon Reduction Strategy that commits the service as a whole to reducing emissions by 60% by 2050. The potential for CHP use in the NHS is huge.
GE wind turbines for Maine’s island communities
Three wind turbines supplied by GE are producing power for the residents of Vinalhaven and North Haven, two year-round communities that comprise the Fox Islands located in Penobscot Bay in mid-coast Maine, US.
The community-owned wind facility, which has three GE 1.5 MW machines on site, was dedicated by project developer, Fox Islands Wind. On average, it is expected to generate 11 GWh of electricity per year, supplying the island’s communities with year-round cleaner, more affordable power.
GE’s 1.5 MW wind turbines are the most widely deployed wind turbines in the world, says the company, with more than 12,000 now installed.
Mitsubishi delivers rooftop PV installation in Italy
Mitsubishi Electric Corporation has completed the installation of an almost 3 MW photovoltaic (PV) installation for Coop’s new CNNA-Prato logistic centre in Prato, Italy. Some 2895 kW of capacity has been installed on the roof, covering a surface of 21,000 square metres.
The system is expected to generate 3.2 GWh per year, which will both meet the entire energy needs of the new logistic centre and also generate an estimated 500,000 kWh excess that will be transferred to the national distribution network.
The installation on the warehouse roof has become the largest rooftop PV system on a single building in Italy. The warehouse roof was specially designed for PV installations, given rooftop installations in Italy receive a higher feed-in tariff rate than those on the ground, and use space effectively. In addition to the rooftop system, an 11 kW system of 60 PV modules has been installed in the parking lot grounds.
Owing to the effectiveness of its PV feed-in tariff programme, the Italian PV market, which reached 258 MW in 2008, has grown to be the third largest in Europe following Germany and Spain, according to the EPIA.
UK government adds CHP requirement
The merits of recovering waste heat from power stations have been enshrined in new UK government planning policy on the development of power plants, says the UK CHP Association. The details, contained within the National Policy Statements (NPS) issued by the Department for Energy and Climate Change (DECC), are said to mark a significant step forward from the Government’s previous treatment of CHP.
Key facets of the new NPS concerning CHP and district heating now include, says the CHPA, an obligation on developers of proposals for new thermal generating stations, to consider the opportunities for CHP from the very earliest point possible, and that these opportunities should be adopted as a locational criterion.
As a result, CHP and district heating are now firmly on the agenda of the new Infrastructure Planning Commission (IPC), as the body established by the UK Government to consider relevant applications for energy developments.

Wärtsilä O&M for Nigerian on-site power plant
Engine manufacturer and supplier of flexible power plants to the decentralized power generation market, Wärtsilä, has been awarded an operations and maintenance (O&M) contract for 10 years by cement manufacturer Lafarge Cement WAPCO to run its cement plant power station in Nigeria.
The O&M contract calls for Wärtsilä to undertake all aspects of operating and maintaining the on-site power plant, including labour, spare parts, scheduled and unscheduled maintenance.
Currently under construction operation in January 2011, the 100 MW power plant is located close to the city of Ewekoro, 65 km north of Lagos. The plant will supply electricity to a new cement works being built there. Lafarge Cement WAPCO will double its capacity to over 4 million tonnes of cement produced by 2011.
The power plant is a turnkey project by Wärtsilä, and will be powered by six Wärtsilä 18V50DF engines that can operate on heavy fuel oil, light fuel oil, or gas. When operational, the Ewekoro power plant will, together with other plants already delivered by Wärtsilä, bring the total combined generating capacity supplied by Wärtsilä to Nigeria to approximately 400 MWe. .
‘On-site utility’ to reduce energy costs at NY complex
American DG Energy has announced a 15-year agreement to supply low cost, clean energy to Linden Plaza Preservation, a 1500-unit, low-income housing complex, located in Brooklyn, New York, US. Linden Plaza, will soon receive a substantial portion of its energy from a 500 kW on-site energy system which will be owned and operated by American DG Energy.
Linden Plaza will receive a discount on the energy produced by what American DG calls an ‘on-site utility’ and reduce its carbon footprint by up to 2400 tonnes of carbon dioxide per year. The energy will be produced with small-scale CHP units located at the property site but owned and operated by American DG. Each of the five towers will have one 100 kW CHP unit, which will operate at a combined efficiency of 90%.
On-site wind for UK chemicals companies
An on-site wind project, comprising two 2.5 MW wind turbines, has begun operation at Solutia Chemicals (UK) in Newport, Wales. The turbines will supply up to a third of the chemical company’s needs.
Solutia is the second chemical industry project to be built by wind specialists Wind Direct, which previously installed two turbines at Eastman Chemicals’ plant in Cumbria to supply approximately 25% of that company’s power needs.
Frankie Karki, Chief Operating Officer for Wind Direct said: ‘The chemical industry has high energy requirements and continuous shift patterns, which make chemical companies ideal candidates for on-site energy. The Wind Direct approach is a zero capital, zero risk approach, so it is proving a major attraction as companies look for ways to reduce their costs.’
Dalkia delivers CHP to 20 UK Tesco stores
Dalkia, through its CHP subsidiary Cogenco, has installed 20 CHP plants across a number of Tesco retail stores in the UK, with more planned as part of Tesco’s plans to halve carbon emissions from its buildings by 2020.
Although more traditionally associated with large-scale manufacturing and other heavy industrial applications, Dalkia is successfully delivering the benefits of CHP to the commercial sector, allowing retailers to improve the impact of their energy requirements in a cost-efficient way.
Typically, a saving of around £45,000 ($71,000) per year can be made on a site operating a 200 kW CHP plant, resulting in a carbon saving of 325 tonnes.
Damian Shevloff, Sales Director of Cogenco said: ‘The installation of small-scale CHP is ideal for retail sites such as Tesco’s stores due to the high demand for both heat and power throughout the day. This provides a financially viable alternative to off-grid energy procurement, while also contributing to Tesco’s green agenda too.’
Fuel cell micro-CHP unit moves into Europe
UK-based Ceramic Fuel Cells has sold its first BlueGen domestic-scale, fuel cell-based CHP units in Europe, to German utility EWE, which has ordered three units, for delivery in Q2 and Q3 this year.
The company has previously announced the proposed installation of similar units into Japan and Australia.
Ceramic Fuel Cells says it has achieved the highest electrical efficiency of any product in the market for small-scale power and heat products. The company has been working with EWE since 2005.
Veolia Energy buys Portland cooling system
Veolia Energy North America has purchased the Portland District Cooling Company from Marubeni Sustainable Energy, making Portland Veolia’s first district energy system in the Pacific Northwest.
The company says it owns and operates the largest portfolio of heating, cooling and cogeneration networks in North America, with systems across the country in Atlanta, Baltimore, Boston, Cambridge, Grand Rapids, Kansas City, Las Vegas, Los Angeles, Oklahoma City, Philadelphia, St. Louis, Trenton and Tulsa. As part of this acquisition, Veolis Energy plans to implement its best practices for preventative maintenance and will continue to invest in the system to increase efficiency.
The Portland district cooling system produces and distributes chilled water to the Brewery Blocks, a five-block shopping and professional district in Portland’s post-industrial Pearl District neighbourhood. The plant, with 4,000 tonnes of installed chilled water capacity, houses two centrifugal chillers along with a state-of-the-art automation system that operates the chillers and controls system devices. Customers who currently utilize chilled water from the system include retail businesses, office buildings, luxury apartments and condos, a large data centre and a performance art hall.
The district cooling system was initially developed by Portland General Electric (PGE), a local electric utility that constructed the district plant and an underground distribution loop from 1999-2001.
Ceres Power takes residential CHP to Ireland
